We have a first amendment. It protects speech. "Laws" against what can and cannot be said in public is not a slippery slope I want to go down, regardless if the person is a lying sack of shit.
As already stated, the voters are supposed to hold these lying sacks of shit accountable by voting out said lying sacks of shit. I think this problem gets dealt with in abolishing first past the pole voting systems.
Aviiiiiiii
